To all whom it may concern:

Be it known that 1,.GnonenFnnnnn1cn SIMonDs, engineer, a citizen of theUnited States, and a resident of Fitchburg, Massachusetts, have inventedcertain new and useful Improvements in Ball-Bearings, of which thefollowing. is a specification, referenc e being had to the accompanyingd -=awings'.

My invention relates to thrust or end-pressio'yure bearings in groups ofspherical rollers or balls are em-v ployed to diminish the friction.

My said invention is chiefly designed to provide simple and efficientmeans for trans. mitting the thrust of screw -propellers to steamships;but my improvements are also applicable to thrust or end-pressurebearings.

for other purposes.

In making athrust-bcaring according to my present invention I provide asuitable collar on the propeller or other shaft, and I arrange on eachside of this collar any desired number of pairs of inner and outer ringsor annular pieces provided with concentric surfaces and plane surfaces,between which are annular channels or cavities wherein the balls arearranged in circular series or groups, one of the said concentricsurfaces and one of the said plane surfaces being formed on each of thesaid rings .or annular pieces.

An important feature of my present invention is the combination, withthe inner and outer rings having, the balls arranged between theirconcentric and plane surfaces, of improved meanswhereby the'outer-ringsmay be adjusted relatively to the inner rings to bring the balls to abearinga'gainst the said.

plane surfaces. 1 so construct the bearingthat the outer ring of eachpair can be adjusted independently of those of the other pairs.

Another important feature of my said i-n' vention is the constructionand arrangement of the parts of the bearing in such a manner thateitherof the outer rings can be moved longitudinally upon thecorresponding inner ring through a sufficient distance to permit theremoval and replacing of the series or group of balls between themwithout disturb.

c care the spherical rollers or balls, which' are arranged in circularseries or groups .between the said rings. It will be seen that thesurfaces a I) of each pair of rings are concentric with each other andwith the shaft A, and that the plane bearing-surfaces a b "of each pairof rings are parallel to each other and perpendicular to-the saidconcentric 'sur:

faces. a The direction of the pressure upon the-balls c c is indicatedmore clearlyby dotted lines passing through the points of contact of theballs withthe said surfaces. The balls 0 roll upon the bearing-surfacesa b when the shaft is rotated, the concentric merely serving to. retainthe balls in place and being arranged at such a distance apart that theballs can work freely between them. By employing the said rings 8othereomas above described, I am enabled to and, advantageously hardenertemper and finish the said surfaces before the parts of the bearing areput togethe z. I

C C are screw-bolts, which extend through holes in the pedestal B, andalso through holes in lugs or fianges' b on all of the duter, Thesebolts are firmly secured in the pedestal .by means of nuts 0, and arethus restrained from end'wise motion relatively to the said pedestal andto the rings 1). On the saidscrew-bolts, in combination with each outerring I), are arranged adjustingmuts D and locking-nuts D, whereby thesaid ring may be accurately adjusted relatively to the 9 5 correspondinginner ring a to bring the balls locked in any position to which they maybe adjusted.
